By End of July. It will be open before the Festival.
It is likely the person being mentioned in John Lewis is the Apple rep..
Took a pic the other day, similar to the other above. The reason for the slightly larger white boards is due to the hotel on the opposite side of the road, they would have been able to see. Someone was actually sent to check it out from the top room in said hotel to make sure it was suitably covered!!
Wish they had cleaned the older section of the building and it will be interesting to see how Apple Photograph the building to 1. mask that difference in colour and 2. to exclude the horrific state of the cobbles and path to the side of the building (West Register Street). The hotel that occupies the upper part opens in 15 days.
This link to the hotel shows what the ground floor unit Apple are to occupy is likely to look like..
